Design and Construction
The hull and deck are solid fibreglass, built by the Australian yard Swarbrick Bros. Yachts Pty Ltd without cored panels. At 8.00 meters overall with a 2.70-meter beam and a design waterline of 7.10 meters, she carries 1,400 kilograms of displacement and 550 kilograms of lead ballast — a 39 percent ballast ratio that, with a length-to-beam ratio of 2.96, marks her as a beamy, firmly planted small racer rather than a slender daysailer. The fin keel draws about 1.40 to 1.50 meters depending on load, which keeps her out of the thinnest shoals but still lets her slip into many modest marinas.
Rig and Sail Plan
The Swarbrick 80 is built with a fractional sloop rig, and the numbers show a boat that is dramatically over-canvased for her size: she carries more rig than 100% of all similar sailboats, which indicates that the boat is significantly overrigged. The reference sail plan gives a mainsail of 18.0 square meters and a No1 genoa of 19.4 square meters, while a 135 percent genoa lifts the sail-area-to-displacement ratio from 24.2 to 27.8. With the standard mainsail and jib combined area of 29.7 square meters and a 51.0-square-meter spinnaker available, the sail wardrobe is serious. Halyards run 25.7 meters with 8 mm diameter; sheets are 10 mm, with the mainsheet at 20 meters and the spinnaker sheets at 17.6 meters.
Performance Character
Her displacement-length ratio of 109 places her among the light racers, and the theoretical hull speed for a boat of her length is 6.5 knots. The Motion Comfort Ratio sits at 10.7, and the capsize screening value is 2.43. The wetted surface is about 22 square meters, and immersion runs about 128 kg per centimeter, so she responds quickly to crew weight and load changes. The combination of light displacement, high sail-area-to-displacement ratio, and a modest comfort number describes a lively inshore performer built for class racing rather than offshore passage work.
The Verdict
The Swarbrick 80 is a purpose-built one-design that delivers racing intensity in a small packet. She is unapologetically overrigged for her length, light on her feet, and strict in her class rules — a boat for sailors who want a measurable, repeatable contest and a simple coastal cruiser in the same hull.
Pros
- Strict one-design racing and cruising platform from 1978
- Light-displacement "light racer" with a high sail-area-to-displacement ratio
- Solid fibreglass hull and deck with lead ballast and fin keel
Cons
- Capsize screening value of 2.43
- Shallow comfort ratio marks her as a lively rather than plush cruiser
- Draft up to 1.50 meters limits the thinnest-water anchorages
